Grooved End Swing Check Valve with UL,FM

Model SCV, RCV grooved end swing check valves are compact and rugged swing-type units that allow water to flow in one direction and prevent flow in the opposite direction. This valve can be installed horizontally or vertically with the flow in the upward direction as well.
When the pressure at the 1st entrance is higher than the restitution force of a spring connected to a crapper, the crapper is pushed up away from the disc and then fluid flows through the gap between the disc and the crapper.
When the pressure at the 1st entrance is lower than the restitution force of a spring connected to the crapper, the spring’s restitution force makes the crapper press the disc, blocking the flow of fluid.
The valve’s body and pipeline can be connected using grooved couplings. It can be installed either horizontally or vertically depending on the flowing direction of fluid. Designed to minimize water hammer noises (sound caused when a fluid in motion is forced to stop or change direction suddenly) that may be generated when fluid flows backward. Functionally scalable design is adopted with a tapping boss installed on the body (a pressure gauge or connectors can be added).
